拍摄照片时预览不会暂停

I have a camera application that I could do with some help with. In my Camera Fragment I call the method takePicture, which I is meant to pause the preview (according to the API).

我有一个相机应用程序,我可以做一些帮助。在我的相机片段中,我调用方法takePicture,我打算暂停预览(根据API)。

On my old HTC One X this was true, but having just upgraded to an HTC One mini2 the preview no longer pauses.

在我的旧HTC One X上这是真的,但刚刚升级到HTC One mini2,预览不再停顿。

Is there a logical reason for this? Any suggested changes to my code?

这有合理的原因吗?我的代码有任何建议的更改吗?

I am calling takePicture with the following code:

我用以下代码调用takePicture:

if (myCamera != null) {

    FragmentManager fm = getFragmentManager();
    PhotoHandler myphotohandler = new PhotoHandler(fm, mycontext, getView(), Photo_Type, photonumber, getDir(Project_Name), lmanager, projecttag);

    ShutterCallback shutter = new ShutterCallback() {
        public void onShutter() {
            button_takephoto = (ImageButton) getView().findViewById(R.id.button_takephoto);
            button_takephoto.setImageResource(R.drawable.shutter_closed);
            }
        };

        myCamera.takePicture(shutter, null, null, myphotohandler);

And my PhotoHandler class implements the PictureCallback.

我的PhotoHandler类实现了PictureCallback。

Any suggestions or similar experiences would be appreciated.

任何建议或类似的经验将不胜感激。

A solution I found is to manually stop the preview in a Camera.ShutterCallback. Originally, I had only a Camera.PictureCallback handling my apps response to a picture being taken.

我找到的解决方案是在Camera.ShutterCallback中手动停止预览。最初,我只有一个Camera.PictureCallback处理我的应用程序对正在拍摄的照片的响应。

        if (myCamera != null) {

            PhotoHandler myphotohandler = new PhotoHandler();

            ShutterCallback shutter = new ShutterCallback() {
                public void onShutter() {
                    myCamera.stopPreview();
                }
            };

            myCamera.takePicture(shutter, null, null, myphotohandler);

        }
